CUTTING DEVICE Filed July 10, 1940 M12 KHz/70 541F515. P fiz'lll' s ATTORNEYS latenteci May 12, 1942 CUTTING DEVICE? Walter C. Athon, Oody ,"and Elijah E. Phillips, i- 'GreybulLWym' Y Application .luly 10, 1940, Serial No. 34439; 2 Claims. (o1. 255-105) V The presentinvention relates to new and useful improvements in cutting devices particularly adapted for use in cutting bituminous materials,-

such as asphalt, tar or the like packaged in drum form. r

The principal object of the invention is to provide a relatively simple and efiicient device of this character which will quickly and easily out such bituminous materials into relatively small sections for placement in a melting pot.

Another. object of the invention is to provide a cutting device having the above characteristics that is portable so as to be carried from one drum of tar or the like to another, such drums being ordinarily spaced an appreciable distance apart when tarring a pipe line, roadway or other analogous uses.

The invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing our invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is an end elevational view of a drum of bituminous material showing the device in use.

Figure 2 is a side elevational view thereof.

Figure 3 is a verticalsectional view taken substantially on line 33 of Figure 2.

Figure 4 is a vertical sectional view taken substantially on line 4-4 of Figure 1.

Referring to the drawing for a more detailed description thereof, there is disclosed a block 5 of bituminous material, such as asphalt, pitch or tar to be cut into sections by the cutting device generally designated by the reference numeral 6, said cutting device adapted to be disposed on the block 5 in the manner shown in Figures 1 and 2 of the drawing.

The cutting device 6 comprises a substantially rectangular-shaped base I having side flanges 8 which extend downwardly therefrom and which are arranged in planes located at opposite sides of and parallel to the plane in which the axis of the block is located. The downward extension of the flanges and their relation to the axis of the block, permit them to engage the tar being cut at opposite sides and thereby hold the device against accidental movement during the cutting operation.

An opening 9 is formed centrally of the base size for placement in 1 and extending upwardly from opposed 'side' walls thereof are a pair of standards H3. The standards In form a support for a drum H, said drum being formed with the conventional retaining flanges l2 mounted adjacent the standards It). One end of the drum II has a ratchet wheel I3 supported thereon adapted to be engaged by apawl l4 pivotally mounted as indicated at IE to one of the standards I0. A shaft I6 is frictionally held within the drum II and projects therefrom as best "shown in Figures 2 and 4 of the drawing, one end of said shaft adapted to receive a conventional ratchet handle I! for ef-' fecting rotation of the drum I l in a clockwise or anti-clockwise direction.

A flexible cutting device in the form of a cable l8 has one end attached as indicated at I!) to a lug 20 formed on the base I, the other end of said cable extending through the opening 9 and attached to a U-shaped bolt 2| extending from one of the flanges l2. The cable i8 is looped around the drum in the manner shown in Figures 1 and 2 of the drawing when using the device for cutting the drum in sections and by rotating the drum H in a clockwise direction, the cable [8 will be wound on the drum H as it cuts through the block of materialfl5.

The cutting device is used as follows: The block 5 is first cut approximately four inches by the use of an axe or thelike, where the desired 7 cut is to be made, after which the base is positioned on the block and the cable looped therearound with a section of the cable placed in the cut. The handle I1 is then operated to rotate the drum II to pull'the cable through the block of tar and wind said cable on the drum H. The average size block of material will be cut into four equal sections which will be of the desired a melting pot. The drum II is adapted to be rotated in an anti-clockwise direction for unreeling the cable to permit its use on subsequent blocks of material.

Also it will be understood, of course, by those skilled in the art that variations in the hereinabove described device involving the substitution of substantial equivalents for the devices described are intended to be comprehended within the spirit of the present invention and that the invention is capable of extended application and is not confined to the exact showing of the drawing nor to the precise construction described and, therefore, such changes and modifications may be made therein as do not afiect the-spirit of the invention nor exceed the scope thereof as expressed in the appended claims.

of the said drum in one direction, a flexible cutting element having one end attached to the base and the opposite end fastened to the drum and adapted to encircle the material, one end of the said drum having a non-circular socket therein, and a ratchet arm detachably engageable with the socket end of thegdrum for turning the drum to tighten the flexible element and cut through the block of material.

2. In a cutting device of the character described, a channel shaped base member, apair tically of the base adjacent the opposed ends thereof, a cylindrical drum extending through and journalled on the said bearing members, the said drum having one end projecting laterally of the base and having a non-circular socket therein, a pair of flanges secured to the drum and disposed adjacent the bearing elements, a ratchet wheel fixed on the drum exteriorly of the bearing elements, a pivoted pawl mounted on the base member operable to engage the ratchet wheel to prevent rotation of the drum in one direction, aflexible cutting cable having one end fastened to the base and the opposite end attached to 'the drum adapted to be looped about the block jof materlal for cutting the same, and a ratchet handle adapted for detachable connection with o, the sock eted end of the drum for rotating the a of bearing members secured to and disposed ver- 20 drum on the base.
